Embodiments of the present disclosure describe a fixing assembly of abone conduction vibrator. In some embodiments, the fixing assembly ofthe bone conduction vibrator may include an elastic fixing portion and afixing member. The elastic fixing portion may be in a band structure.The fixing member may fix the elastic fixing portion around a wearingobject so that the bone conduction vibrator is set between the elasticfixing portion and the wearing object, and the elastic fixing portionpresses the bone conduction vibrator against the wearing object toachieve contact between the bone conduction vibrator and the wearingobject, thereby ensuring that the bone conduction vibrator can output anaudio signal (e.g., a bone conduction sound wave) to the wearing objectby transmitting vibration to the wearing object. In some embodiments,the fixing member is fixed to a first end of the elastic fixing portionand is detachably fixed to a second end of the elastic fixing portion,and a position where the fixing member is detachably fixed to the secondend of the elastic fixing portion is adjustable, so that a length of theelastic fixing portion worn around the wearing object is adjustable, andthus a pressure between the elastic fixing portion and the wearingobject can be adjusted. For example, the fixing member is a buckle, thesecond end of the elastic fixing portion is provided with multiplebuckle holes disposed at intervals along a length direction of theelastic fixing portion. The detachable fixing of the fixing member andthe elastic fixing portion is realized by the cooperation of the buckleand the buckle holes. As another example, the fixing member is anadhesive buckle member including a gross surface and a hook surface. Thedetachable fixing of the fixing member and the elastic fixing portion isrealized by the cooperation of the gross surface and the hook surface.As a further example, the fixing member is a ring buckle, and the secondend of the elastic fixing portion is provided with multiple buckle slotsdisposed at intervals along the length direction thereof, and thedetachable fixing of the fixing member and the elastic fixing portion isrealized by the cooperation between the ring buckle and the buckleslots.

In some embodiments, the elastic fixing portion may include a firstposition and a second position on the second end. The first position andthe second position are disposed at intervals along the length directionof the elastic fixing portion. When the fixing member fits into thefirst position of the elastic fixing portion, the elastic fixing portionsurrounds the wearing object and is in a natural state. When the fixingmember fits into the second position, the elastic fixing portionprovides the bone conduction vibrator with appropriate pressure on thewearing object. The pressure is within a preset pressure range so as tomake the wearing object more comfortable while receiving an audio signaleffectively. In some embodiments, a product of a distance between thefirst position and the second position and an elastic coefficient of theelastic fixing portion is within the preset pressure range, and thematching position of the fixing member and the elastic fixing portionmay be adjusted between the first position and the second position sothat the pressure provided by the elastic fixing portion for the boneconduction vibrator is always within the preset pressure range.

In some embodiments, the fixing assembly may be used for bone conductionvibrator testing. Specifically, when conducting a bone conductionvibrator test, the bone conduction vibrator may be fixed to the wearingobject (e.g., a human body, a guinea pig, etc.) by the fixing assembly.The bone conduction vibrator outputs an audio signal to the wearingobject, and a feedback signal generated by the wearing object inresponse to the audio signal output by the bone conduction vibrator maybe detected. The signal transmission performance of the bone conductionvibrator may be judged by the feedback signal. In some embodiments, whenan intensity of the detected feedback signal is greater than or equal toa preset signal intensity, it can be considered that the audio signaltransmission performance of the bone conduction vibrator is relativelygood, and can make the wearing object effectively obtain informationcontained in the audio signal after receiving the audio signal. In someembodiments, a pressure between the wearing object and the boneconduction vibrator or the fixing assembly may be detected. A pressureset including intensities of the feedback signals is greater than orequal to the preset signal intensity is taken as a preset pressurerange.

In some embodiments, the fixing assembly may also be used for thewearing of an acoustic output device. Specifically, the acoustic outputdevice may include a bone conduction vibrator. During the activity ofthe wearing object, the fixing assembly may maintain the acoustic outputdevice in relative fixation and/or contact with the head of the wearingobject at all times, so that an audio signal output by the acousticoutput device may be transmitted to the wearing object and be perceivedby the auditory nerves of the human body. In some embodiments, thefixing assembly may also be used for the wearing of other devices (e.g.,an electronic device). For example, the fixing assembly may be used forthe wearing of a watch, an oximeter, a blood pressure monitor, apedometer, and other devices.

FIG. 1 is a block diagram illustrating a fixing assembly of an exemplarybone conduction vibrator according to some embodiments of the presentdisclosure. As shown in FIG. 1 , the fixing assembly 100 of the boneconduction vibrator may include an elastic fixing portion 110 and afixing member 120. The elastic fixing portion 110 is a structure withelasticity made of an elastic material. The elastic fixing portion 110has a tensioning force due to its elasticity, thereby providing apressure for the bone conduction vibrator to act on the wearing object,wherein the tensioning force of the elastic fixing portion 110 may beapproximated as a pressure of the bone conduction vibrator acting on thewearing object. In some embodiments, a pressure of the bone conductionvibrator acting on the wearing object may be determined by determiningthe tensioning force of the elastic fixing portion 110. The tensioningforce (the pressure of the bone conduction vibrator acting on thewearing object) of the elastic fixing portion 110 is calculated by thefollowing equation:

F=k×x   (1)

where F denotes the pressure of the bone conduction vibrator acting onthe wearing object; k denotes an elastic coefficient of the elasticfixing portion 110, and x denotes the deformation generated by theelastic fixing portion 110.

The elastic coefficient of the elastic fixing portion 110 is related toa thickness, a length, a width, a shape, and a material of the elasticfixing portion 110. In some embodiments, the elastic coefficient of theelastic fixing portion 110 may be adjusted by adjusting any one or moreof the thickness, length, width, shape, and material of the elasticfixing portion 110 to achieve adjustment of the pressure of the boneconduction vibrator acting on the wearing object.

In some embodiments, the thickness of the elastic fixing portion 110 maybe in a range of 0.6 mm-2 mm. In some embodiments, the thickness of theelastic fixing portion 110 may be in the range of 0.7 mm-1.5 mm. In someembodiments, the thickness of the elastic fixing portion 110 may be inthe range of 0.8 mm-1.2 mm. In some embodiments, the thickness of theelastic fixing portion 110 may be in the range of 0.9 mm-1.0 mm. In someembodiments, the thickness of the elastic fixing portion 110 is 0.8 mm,1.1 mm, or 1.2 mm, etc. Preferably, the thickness of the elastic fixingportion 110 may be 1.2 mm. It should be noted that the thickness of theelastic fixing portion 110 may also be other thicknesses (e.g., lessthan 0.6 mm or greater than 2 mm), which is not specifically limited bythe present disclosure.

In some embodiments, the elastic material of the elastic fixing portion110 may include a silicone material. In some embodiments, the siliconematerial may include, but is not limited to, any one or more of: a 10degree silicone 50% high tensile silicone material, a 20 degree silicone50% high tensile silicone material, a 30 degree silicone 50% hightensile silicone material, a 10 degree silicone 70% high tensilesilicone material, a 20 degree silicone 70% high tensile siliconematerial, a 30 degree silicone 70% high tensile silicone material, a 10degree silicone 1% high tensile silicone material, a 20 degree silicone1% high tensile silicone material or a 30 degree silicone 1% hightensile silicone material. It should be noted that in other embodimentsof the present disclosure, the elastic fixing portion 110 may also bemade of other materials, such as polycarbonate, polyamide, rubber, etc.,and is not specifically limited herein.

The elastic coefficients with respect to different (e.g., differentthicknesses and/or materials) elastic fixing portions 110 may beobtained by pretesting, and the testing method may be performed asfollows including: obtaining an elastic band of the same material,thickness, and width as the elastic fixing portion 110, applying apreset value of tensile force to the elastic band by a tensiometer todeform the elastic band, measuring the deformation of the elastic band,and calculating the elastic coefficient k according to equation (1),i.e., the elastic coefficient k is equal to the preset value of tensileforce divided by the deformation of the elastic band.

In some embodiments, the elastic fixing portion 110 may be a bandstructure. A first position and a second position are disposed atintervals along the length direction thereof on the elastic fixingportion 110, and the first position and the second position of theelastic fixing portion 110 may be matched with the fixing member 120 soas to adjust the elastic fixing portion to provide the bone conductionvibrator with a pressure acting on the wearing object. For example, theelastic fixing portion 110 surrounds a particular part (e.g., a head) ofthe wearing object, wherein when the fixing member 120 fits into thefirst position of the elastic fixing portion 110, the elastic fixingportion 110 is in a natural state. As another example, when the fixingmember 120 fits into the second position, the elastic fixing portion 110provides a pressure to the bone conduction vibrator that acts on thewearing object and the pressure is within a preset pressure range. Thenatural state may be understood that the fixing assembly 100 maysurround a particular part of the wearing object, and the boneconduction vibrator provides a pressure acting on the wearing objectthat is less than a particular pressure (e.g., 0.2 N). In someembodiments, the elastic fixing portion 110 may include a band body thatmay be surrounded and fixed around the wearing object under the actionof the fixing member 120.

For more informationabout the first band body and the second band body, please refer to FIG.6 and related descriptions.

The fixing member 120 is configured to fix the elastic fixing portion110 round the wearing object. A matching position between the fixingmember 120 and the elastic fixing portion 110 may be adjusted betweenthe first position and the second position of the elastic fixing portion110, which may allow the elastic fixing portion 110 to provide apressure to the bone conduction vibrator that is always within thepreset pressure range. In some embodiments, the preset pressure range is0.2N-2N. In some embodiments, the preset pressure range may be 0.5N-2N.Preferably, the preset pressure range may be 0.8N-2N. More preferably,the preset pressure range may be 1.2N-1.8N.

In some embodiments, the fixing member 120 may be a buckle, and thebuckle cooperates with one or more buckle holes on the elastic fixingportion 110 to achieve detachable fixing between the fixing member 120and the elastic fixing portion 110. The first position may be a positionof a buckle hole or any other position on the elastic fixing portion 110(e.g., between buckle holes), and the second position may be a positionof a buckle hole with a certain distance from the first position. Theposition of the buckle hole that fits with the buckle may be adjusted toadjust a tension degree of the elastic fixing portion 110 around thewearing object, thereby enabling adjustment of the magnitude of thepressure applied to the wearing object by the bone conduction vibratorlocated between the elastic fixing portion 110 and the wearing object.For more information about the buckle and buckle holes, please refer toFIG. 3 and related descriptions. In some embodiments, the fixing member120 is an adhesive buckle member. The fixing member 120 may include agross surface structure.

The first position may be a position of a certain hook surface orany other position on the elastic fixing portion 110 (for example, aposition between hook surfaces), and the second position may be aposition of a hook surface at a certain distance from the firstposition. The position of the hook surface located at one end thatcooperates with the gross surface located at another end may be adjustedto adjust a tension degree of the elastic fixing portion 110 around thewearing object, thereby enabling adjustment of the magnitude of thepressure applied to the wearing object by the bone conduction vibratorlocated between the elastic fixing portion 110 and the wearing object.For more information about the gross surface and the hook surface,please refer to FIG. 4 and related descriptions. In some embodiments,the fixing member 120 may be a ring buckle, and the ring bucklecooperates with a slot on the elastic fixing portion 110 to achieve thedetachable fixing between the fixing member 120 and the elastic fixingportion 110.

The fixing assembly is illustrated exemplarily below in conjunction withFIGS. 2 and 3 . FIG. 2 is a schematic diagram illustrating a structureof a fixing assembly according to some embodiments of the presentdisclosure. FIG. 3 is a schematic diagram illustrating a structure of afixing assembly according to some further embodiments of the presentdisclosure. As shown in FIG. 2 and FIG. 3 , in some embodiments, afixing assembly 200 may include an elastic fixing portion 210 and afixing member 220. In some embodiments, the elastic fixing portion 210may be a band structure, and the elastic fixing portion 210 is providedwith multiple buckle holes 211 disposed at intervals along the lengthdirection (X direction shown in FIG. 2 ) of the band structure.Correspondingly, the fixing member 220 may be a buckle member, and thefixing member 220 may include a buckle 221. The buckle 221 is fixed toone end of the elastic fixing portion 210. The fixing member 220 and theother end of the elastic fixing portion 210 are detachably fixed byinserting the buckle 221 into the buckle holes 211. By adjusting thebuckle 221 into the buckle holes 211 at different positions, the tensiondegree of the elastic fixing portion 210 around the wearing object maybe adjusted, so as to achieve the adjustment of the pressure of the boneconduction vibrator located between the elastic fixing portion 210 andthe wearing object acting on the wearing object. Specifically, thecloser the buckle 221 buckles into the buckle holes 211 to one end ofthe elastic fixing portion 210 away from the fixing member 220, thesmaller the pressure. It should be understood that one end of theelastic fixing portion 210 and the other end of the elastic fixingportion 210 of this embodiment may be the opposite ends of the bandstructure or may refer to the opposite ends after truncating thecircular elastic fixing portion 210 from a certain position.

In some embodiments, the elastic fixing portion 210 is a rubber bandwith elasticity. In some embodiments, the multiple buckle holes 211provided on the elastic fixing portion 210 away from one end of thefixing member 220 are equally arranged.

In some embodiments, the buckle 221 mayinclude a base, a mushroom head-like structure, and a connection column,wherein the mushroom head-like structure is connected to the base viathe connection column. In some embodiments, the mushroom head-shapedstructure may be a hemisphere, wherein a diameter of the hemisphere islarger than a diameter of the buckle hole 211, and the elastic fixingportion 210 is a structure with elasticity, so that the mushroomhead-shaped structure may be passed through the buckle hole 211 by anexternal force, so that when the buckle 221 is inserted into the buckleholes 211, the buckle hole 211 cooperates with the connection column,and the mushroom head-shaped structure and the base play a limitingrole, thereby preventing the elastic fixing portion 210 from detachingfrom the buckle 221. Merely by way of example, the diameter of thebuckle hole 211 may be 3 mm and the diameter of the mushroom head may be4 mm. It should be understood that the shape and size of the buckle 221may be varied according to actual needs, for example, the diameter ofthe hemisphere may be other sizes; alternatively, the buckle 221 mayalso be a structure such as a hook with one end in the shape of a hook.

In some embodiments, the elastic fixing portion 210 may include a firstposition and a second position in sequence along the length direction ofthe elastic fixing portion 210. The first position is a position wherethe fixing member 220 is connected to the elastic fixing portion 210when the elastic fixing portion 210 surrounds a test wearing object andis in its natural state, and the second position is a position where thefixing member 220 is connected to the elastic fixing portion 210 whenthe elastic fixing portion 210 surrounds the test wearing object andprovides a pressure within a preset pressure range for the boneconduction vibrator to act on the test wearing object.

In some embodiments, the multiple buckle holes 211 may include at leastone fixing buckle hole, and a position where the fixing buckle hole islocated is the second position. When the buckle 221 is buckled into thefixing buckle hole, the elastic fixing portion 210 can be worn aroundthe wearing object and the fixing member 220 can be fixed at the secondposition. The second position may be any position on the elastic fixingportion 210, which only needs to meet: a product of a distance betweenthe second position and the first position, and the elastic coefficientk of the elastic fixing portion 210 is between a minimum threshold ofthe pressure of the bone conduction vibrator on the wearing object and amaximum threshold of the pressure of the bone conduction vibrator on thewearing object. Thus, a count of the second positions may be one ormore. When there are multiple fixing buckle holes, the count of thesecond positions is also multiple, and each position where the fixingbuckle hole is located is one second position, i.e., the product of thedistance between each fixing buckle hole and the first position and theelastic coefficient of the elastic fixing portion 210 is between theminimum threshold of the tensioning force and the maximum threshold ofthe tensioning force.

In some embodiments, a distance between two adjacent buckle holes 211 ofthe multiple buckle holes 211 is x₂. That is, when the buckle 221 ismoved out from one buckle hole 211 and buckles into another buckle hole211 adjacent to that buckle hole 211, an increment of the tensioningforce of the elastic fixing portion 210 is F₀=k×x₂. By adjusting themagnitude of the elastic coefficient k of the elastic fixing portion 210and the distance x₂ between the two adjacent buckle holes 211, theincrement of the tensioning force F₀ when the deformation of the elasticfixing section 210 is increased to x₂ may be adjusted. By adjusting theposition of the buckle hole 211 where the buckle 221 is inserted, thedeformation of the elastic fixing portion 210 may be adjusted, and aproduct of the deformation of the elastic fixing portion 210 and theelastic coefficient of the elastic fixing portion 210 is the magnitudeof the tensioning force of the elastic fixing portion 210. Therefore,according to the position of the buckle hole 211 where the buckle 221 isinserted, it is easy to determine the magnitude of the tensioning forceof the elastic fixing portion 210, thereby determining the magnitude ofthe pressure of the bone conduction vibrator on the wearing objectwithout the use of a measuring instrument, etc., and simplifying theoperation steps for bone conduction testing. Moreover, by adjusting theposition of the buckle hole 211 where the buckle 221 is inserted, thepressure of the bone conduction vibrator on the wearing object may beadjusted easily and precisely so as to ensure that the pressure of thebone conduction vibrator on the wearing object is within the presetpressure range (i.e., between a minimum pressure threshold and a maximumpressure threshold).

By way of exemplary illustration only, the multiple buckle holes 211 mayinclude a first buckle hole 212, a second buckle hole 213, and a thirdbuckle hole 214. The third buckle hole 214, the first buckle hole 212,and the second buckle hole 213 are provided adjacent to each other andare arranged sequentially along a direction of the elastic fixingportion 210 away from the fixing member 220. The direction (X-directionshown in FIG. 2 ) of the elastic fixing portion 210 away from the fixingmember 220 refers to a direction along the length direction of theelastic fixing portion 210 from one end where the fixing member 220 islocated to one end where the buckle hole 211 is located. A distancebetween adjacent buckle holes 211 is x₂, i.e., the distance between thethird buckle hole 214 and the first buckle hole 212 and the distancebetween the second buckle hole 213 and the first buckle hole 212 are x₂.When the deformation of the elastic fixing portion 210 increases by eachx₂, the tensioning force of the elastic fixing portion 210 increases byF₀.

As shown in FIG. 2 , in some embodiments, the first position may belocated between any two adjacent buckle holes 211, the fixing bucklehole (i.e., the second position) is the m-th buckle hole 211 from thefirst position. When the buckle 221 is inserted into the fixing bucklehole, the pressure is denoted as F₀×(x₁/x₂+m−1), wherein F₀×(x₁/x₂+m−1)is within the preset pressure range, x₁ denotes a distance between the1st buckle hole at a side away from the fixing member 210 along adirection in which the elastic fixing portion 210 is away from thefixing member 220 and the first position, x₂ denotes the distancebetween two adjacent buckle holes 211, and F₀ denotes the tensioningforce of the elastic fixing portion 210 when the deformation of theelastic fixing portion 210 is equal to the distance between two adjacentbuckle holes 211.

Specifically, as shown in FIG. 2 , the first position is located betweenthe third buckle hole 214 and the first buckle hole 212, and when thebuckle 221 inserts into the first buckle hole 212, the deformation ofthe elastic fixing portion 210 is denoted as x=x₁ and the pressure ofthe bone conduction vibrator on the wearing object is denoted asF=k×x₁=F₀×(x₁/x₂). When the buckle 221 is inserted into the secondbuckle hole 213, the deformation of the elastic fixing portion 210 isdenoted as x=x₁+x₂, and the pressure of the bone conduction vibrator onthe wearing object may be determined as F=F₀×(x₁/x₂+1); when the buckle221 inserts into the n-th buckle hole 211 on a side of the firstposition away from the side of the fixing member 220 along the directionin which the elastic fixing portion 210 is away from the fixing member220, the pressure of the bone conduction vibrator on the wearing objectis denoted as F=F₀×(x₁/x₂+n−1). n is a natural number greater than 0.When the buckle 221 is inserted into different buckle holes 211, sincethe pressure of the bone conduction vibrator on the wearing object canbe determined according to the equation: F=F₀×(x₁/x₂+n−1), it is notnecessary to know the pressure of the bone conduction vibrator on thewearing object by other testing methods, thereby simplifying theoperation steps of bone conduction vibrator testing. Moreover, byadjusting the position of the fixing buckle hole, the pressure of thebone conduction vibrator on the wearing object may be easily andprecisely adjusted, and it is possible to ensure that the pressure ofthe bone conduction vibrator on the wearing object is within the presetpressure range. Herein, the fixing buckle hole is the m-th buckle hole211 on the side of the first position away from the fixing member 220along the direction in which the elastic fixing portion 210 is away fromthe fixing member 220. When the buckle 221 is inserted into the fixingbuckle hole, the pressure of the bone conduction vibrator on the wearingobject is m×F₀, where m×F₀ is within the preset pressure range, m isalso a natural number greater than 0, and m denotes several specificnatural numbers among the natural numbers referred to by n. It should benoted that the fixing buckle holes may be some specific buckle holesamong the multiple buckle holes 211, and when the buckle 221 is insertedinto the fixing buckle hole, the pressure of the bone conductionvibrator on the wearing object is within the preset pressure range.

Merely by way of example, the preset pressure range of the boneconduction vibrator on the wearing object is 0.6N-1.2N, i.e., theminimum pressure threshold of the bone conduction vibrator on thewearing object is 0.6N and the maximum pressure threshold of the boneconduction vibrator on the wearing object is 1.2N. F₀ is 0.6N, i.e.,when the deformation of the elastic fixing portion 210 is the same asthe distance between the adjacent buckle holes 211, the variation of thetensioning force of the elastic fixing portion 210 is 0.6N. When thebuckle 221 is inserted into the second buckle hole 213 as shown in FIG.2 , the tensioning force of the elastic fixing portion 210 is0.6×(x₁/x₂+1), which is within the preset pressure range of 0.6N-1.2N.In this case, n=2, i.e., the 2nd buckle hole 211 on the side of thefirst position away from the fixing member 220 along the direction inwhich the elastic fixing portion 210 is away from the fixing member 220is the fixing buckle hole.

When adjusting the value of the distance x₂ between two adjacent buckleholes 211, and/or adjusting the value of the elastic coefficient k ofthe elastic fixing portion 210, the value of F₀ may be changed, and theposition of the fixing buckle hole may be changed accordingly. Forexample, the value of F₀ is adjusted to 0.3N. At this time, thetensioning force of the elastic fixing portion 210 is 0.3×(x₁/x₂+n−1),and when n is 3 or 4, the tensioning force of the elastic fixing portion210 is within the threshold range of 0.6N-1.2N. In some embodiments, mmay be 3 or 4, i.e., the 3rd buckle hole 211 and the 4th buckle hole 211on the side of the first position away from the fixing member 220 alongthe direction in which the elastic fixing portion 210 is away from thefixing member 220 are fixing buckle holes. When the buckle 221 isinserted into the 3rd buckle hole 211 or the 4th buckle hole 211, it canensure that the tensioning force of the elastic fixing portion 210 iswithin the threshold range, thus ensuring that the pressure of the boneconduction vibrator on the wearing object is within the preset pressurerange. Moreover, when the buckle 221 is inserted into the 3rd bucklehole 211, it is easy to know that the tensioning force of the elasticfixing portion 210 is 0.6N-0.9N; when the buckle 221 is inserted intothe 4th buckle hole 211, it is easy to know that the tensioning force ofthe elastic fixing portion 210 is 0.9N-1.2N.

In some embodiments, the first position may be located at a position ofany one of the buckle holes 211. The fixing buckle hole is the m-thbuckle hole 211 on the side of the first position away from the fixingmember 220 along the direction in which the elastic fixing portion 210is away from the fixing member 220. When the buckle 221 is inserted intothe fixing buckle hole, the pressure of the bone conduction vibrator onthe wearing object is m×F₀, where m×F₀ is within the preset pressurerange.

Specifically, as shown in FIG. 3 , the elastic fixing portion 210surrounds the wearing object. When the elastic fixing portion 210 is inits natural state, the buckle 221 corresponds to the position of thethird buckle hole 214. That is, in this embodiment, the first positionof the elastic fixing portion 210 is a position where the third bucklehole 214 is located. When the buckle 221 is inserted into the first hole212, it is known that the pressure of the bone conduction vibrator onthe wearing object is F=k×x₂=F₀; when the buckle 221 is inserted intothe second hole 213, it is known that the pressure of the boneconduction vibrator on the wearing object is F=k×2x₂=2F₀; when thebuckle 221 is inserted into the n-th buckle hole 211 on the side of thefirst position away from the fixing member 220 along the direction inwhich the elastic fixing portion 210 is away from the fixing member 220,the pressure of the bone conduction vibrator on the wearing object isF=nF₀. When the buckle 221 is inserted into different buckle holes 211,since the pressure of the bone conduction vibrator on the wearing objectcan be determined according to the equation: F=nF₀, it is not necessaryto know the pressure of the bone conduction vibrator on the wearingobject by other testing methods, thereby simplifying the operation stepsof bone conduction vibrator testing. Moreover, by adjusting the positionof the fixing buckle hole, the pressure of the bone conduction vibratoron the wearing object may be easily and precisely adjusted, and it ispossible to ensure that the pressure of the bone conduction vibrator onthe wearing object is within the preset pressure range.

Merely by way of example, the threshold range of the pressure of thebone conduction vibrator on the wearing object is 0.6N-1.2N, i.e., aminimum threshold of the pressure of the bone conduction vibrator on thewearing object is 0.6N, and a maximum threshold of the pressure of thebone conduction vibrator on the wearing object is 1.2N. F₀ is 0.6N,i.e., when the deformation of the elastic fixing portion 210 is the sameas the distance between the adjacent buckle holes 211, the variation ofthe tensioning force of the elastic fixing portion 210 is 0.6N. In theembodiment shown in FIG. 3 , the buckle 221 may be selected to beinserted into the 1st buckle hole 211 or the 2nd buckle hole 211 on theside of the first position away from the fixing member 220 along thedirection in which the elastic fixing portion 210 is away from thefixing member 220. When the buckle 221 is inserted in the 1st bucklehole 211 on the side of the first position away from the fixing member220 along the direction in which the elastic fixing portion 210 is awayfrom the fixing member 220, the tensioning force of the elastic fixingportion 210 is 0.6N; when the buckle 221 is inserted into the 2nd bucklehole 211 on the side of the first position away from the fixing member220 along the direction in which the elastic fixing portion 210 is awayfrom the fixing member 220, the tensioning force of the elastic fixingportion 210 is 1.2N, thus ensuring that the tensioning force of theelastic fixing portion 210 is within the threshold range of 0.6N-1.2N.In this implementation, m may be 1 or 2, i.e., both the 1st buckle hole211 and the 2nd buckle hole 211 on the side of the first position awayfrom the fixing member 220 along the direction in which the elasticfixing portion 210 is away from the fixing member 220 are the fixingbuckle holes in this embodiment.

When adjusting the distance x₂ between two adjacent buckle holes 211,and/or adjusting the elastic coefficient k of the elastic fixing portion210, the value of F₀ may be changed, and the position of the fixingbuckle hole may be changed accordingly. For example, the value of F₀ isadjusted to 0.3N. At this time, the tensioning force of the elasticfixing portion 210 is 0.3 n, and when n is 2, 3, or 4, the tensioningforce of the elastic fixing portion 210 is within the threshold range0.6N-1.2N. At this time, m may be equal to 2, 3, or 4, i.e., the 2ndbuckle hole 211, the 3rd buckle hole 211, and the 4th buckle hole 211 onthe side of the first position away from the fixing member 220 along thedirection in which the elastic fixing portion 210 is away from thefixing member 220 are all fixing buckle holes in this embodiment. Whenthe buckle 221 is inserted into the 2nd buckle hole 211, the 3rd bucklehole 211, and the 4th buckle hole 211 on the side of the first positionaway from the fixing member 220 along the direction in which the elasticfixing portion 210 is away from the fixing member 220, the tensioningforce of the elastic fixing portion 210 can be ensured to be within thethreshold value, thereby ensuring that the pressure of the boneconduction vibrator on the wearing object is within the preset pressurerange. Moreover, when the buckle 221 is inserted into the 2nd bucklehole 211, it is easy to know that the tensioning force of the elasticfixing portion 210 is 0.6N; when the buckle 221 is inserted into the 3rdbuckle hole 211, it is easy to know that the tensioning force of theelastic fixing portion 210 is 0.9N; when the buckle 221 is inserted intothe 4th buckle hole 211, it is easy to know that the tensioning force ofthe elastic fixing portion 210 is 1.2N.

It should be noted that a distance between buckle holes 211 may be adistance between centers of the buckle holes 211. A distance between abuckle hole 211 and the first position may be a distance from the centerof the buckle hole 211 to a central axis of the buckle 221 when theelastic fixing portion 210 is worn around the wearing object and theelastic fixing portion 210 is in the natural state.

In some embodiments, the pressure F of the bone conduction vibrator onthe wearing object may be within a preset pressure range. In someembodiments, the preset pressure range may be 0.2 N-2 N. In someembodiments, the preset pressure range may be 0.3 N-1.8 N. Preferably,the preset pressure range may be 0.4 N-1.6 N. More preferably, thepreset pressure range may be 0.5 N-1.5 N. The range of pressure F may beadjusted depending on different wearing objects. A preferred range ofthe preset pressure range may be 0.6 N-1.2 N, i.e., a minimum thresholdof the preset pressure range is 0.6 N and a maximum threshold of thepreset pressure range is 1.2 N. By cooperating the elastic fixingportion 210 with the fixing member 220, the elastic fixing portion 210generates the pressure F between the minimum threshold and the maximumthreshold, so as to ensure that the elastic fixing portion 210 cangenerate the pressure F within the threshold range. At the same time, byadjusting the elastic coefficient of the elastic fixing portion 210 anda hole spacing L between the two adjacent buckle holes 211, themagnitude of the pressure F and the variation range of the pressure Fcan be adjusted to provide a more accurate pressure F and improve thefixing effect of the elastic fixing portion 210.

In some embodiments, the fixing member 220 may be replaced with a pin(not shown in the figures). The pin has a columnar structure protrudingrelative to its main structure. The multiple buckle holes 211 may bereplaced with multiple boxes (not shown in the figures) correspondingly,and the middle of the box is provided with a hole that matches thecolumnar body of the pin. Specifically, the hole is in a shape of agroove. The columnar body of the pin and the hole of the box cooperateto achieve the fixing of the elastic fixing portion and the fixingmember. Multiple boxes are distributed on the elastic fixing portionalong the length direction of the elastic fixing portion. The pin isfixed at one end of the elastic fixing portion. The fixing member andthe other end of the elastic fixing portion are detachably fixed byinserting the pin into the box. By adjusting the pin to insert into theboxes at different positions, the tensioning degree of the elasticfixing portion worn around the wearing object can be adjusted, so as torealize the adjustment of the pressure of the bone conduction vibratorlocated between the elastic fixing portion and the wearing object actingon the wearing object. The specific positions and structures of the boxand the pin are similar to the fixing assembly shown in FIG. 2 and FIG.3 and can be referred to accordingly.

It should be known that the fixing member may also be of otherstructures. For example, the fixing member may be a coiled structure. Byadjusting a length of the coiled elastic fixing portion, the tensioningdegree of the elastic fixing portion worn around the wearing object maybe adjusted. As another example, the fixing member is a buckle memberwith a buckle tooth. The elastic fixing portion includes multiple buckleslots disposed at intervals. By adjusting the buckle member to be fixedin different buckle slots, the tensioning degree of the elastic fixingportion worn around the wearing object may be adjusted.

The gross surface421 and the hook surface(s) 422 adhere to each other to achieve thefixing of the elastic fixing portion 410 worn around the wearing objectby the fixing member 420. By adjusting the gross surface 421 to adhereto the hook surface(s) 422 at different positions, the tensioning degreeof the elastic fixing portion 410 worn around the wearing object can beadjusted, thereby realizing the adjustment of the pressure of the boneconduction vibrator located between the elastic fixing portion 410 andthe wearing object acting on the wearing object.

Specifically, thefirst band body 611, the second band body 612, and the connection bandbody 613 are combined to form an elastically stretchable “

”-shaped belt. When the first band body 611 and the second band body 612elastically surround the wearing object, both sides are stretched at thesame distance to make the overall deformation of the first band body 611and the second band body 612 relatively uniform.

In some embodiments, a number of connection band bodies 613 may be oneor more. For example, if the number of connection band bodies 613 isone, the connection band body 613 may be provided at a central positionalong a length direction of the first band body 611 and the second bandbody 612 or at any other position.

The mushroom head-shapedstructure may be passed through the buckle hole by an external force, sothat when the first buckle 621 and the second buckle 622 arerespectively inserted into the fourth buckle hole 6111 and the fifthbuckle hole 6121, the elastic fixing portion is prevented from detachingfrom the fixing member 620.

In some embodiments, the fixing member 620 may be fixedly provided onthe bone conduction vibrator. In some embodiments, the connectionportion may be a fixing material that fixes the fixing member 620 to theside of the bone conduction vibrator away from the wearing object. Insome embodiments, the fixing material may be glue or any other materialthat achieves a fixed connection between the buckle and the boneconduction vibrator.

FIG. 13 is a schematic diagram illustratingstructures of the elastic fixing portion, the fixing base, and thefixing member illustrated in FIG. 9 .

As shown in FIG. 9 , in some embodiments, an elastic fixing portion 910may include a first band body 911, a second band body 912, a third bandbody 913, and a fixing member 920. One end of the first band body 911and one end of the second band body 912 are collectively connected tothe third band body 913, and the other end of the first band body 911and the other end of the second band body 912 are collectively connectedto the fixing member 920. In embodiments where the fixing assembly 900is used for bone conduction vibrator testing, a guinea pig may be usedas an example of a wearing object for illustration. The first band body911 may be used to at least partially elastically surround the head ofthe lab rat, and the second band body 912 is used to at least partiallyelastically surround the neck of the lab rat. In some embodiments, thefirst band body 911 is elastically surrounded around the head of the labrat on the front side of the lab rat's ear, and the second band body 912is elastically surrounded around the neck of the lab rat on the backside of the lab rat's ear. The connection portion (not shown in thefigures) is provided on a side of the bone conduction vibrator away fromthe lab rat to connect to the elastic fixing portion 910 and to fix thebone conduction vibrator to the head of the lab rat. In someembodiments, the connection portion and the elastic fixing portion 910may fix the bone conduction vibrator to any other position on the headof the lab rat. Specifically, to fix the bone conduction vibrator to thetop of the lab rat's head using the elastic fixing portion 910 and theconnection portion, the bone conduction vibrator with the connectionportion is first set on the top of the lab rat's head, for example, inthe center of the top of the lab rat's head, so that a distance from thebone conduction vibrator to the left ear of the lab rat is equal to adistance from the bone conduction vibrator to the right ear of the labrat. Secondly, the first band body 911 of the elastic fixing portion 910is elastically surrounded on the front side of the ear of the lab rat,and the second band body 912 of the elastic fixing portion 910 iselastically surrounded on the back side of the ear of the lab rat. Byarranging the first band body 911 and the second band body 912, the labrat's ear may be placed between the first band body 911 and the secondband body 912 while the bone conduction vibrator is fixed near the earof the lab rat, thereby preventing the lab rat's ear from interferingwith the wearing of the fixing assembly 900.

In some embodiments, the third band body 913 is provided with sixthbuckle holes 914 disposed at intervals along the length direction of thethird band body 913. Specifically, the third band body 913 is providedwith multiple groups of sixth buckle holes 914 disposed at intervalsalong its length direction. Each group of sixth buckle holes 914includes at least two sixth buckle holes 914 disposed at intervals alonga width direction of the third band body 913. The same group of sixthbuckle holes 914 is provided with an indication mark 915 between them.In some embodiments, the indication mark 915 may be one or more of blindholes, characters, numbers, colors, etc. In some embodiments, the sixthbuckle holes 914 may be triangular, square, polygonal, track-shaped,etc. The shapes of the multiple sixth buckle holes 914 may all be thesame or partially the same.

As shown in FIG. 10 , the fixing member 920 may be a buckle member. Insome embodiments, the fixing member 920 may include a fixing base 923, afirst buckle 921, and a second buckle 922. The first buckle 921 and thesecond buckle 922 are disposed at intervals on the fixing base 923. Thefirst buckle 921 and the second buckle 922 may be inserted into eachgroup of sixth buckle holes 914. The first buckle 921 and the secondbuckle 922 cooperate with the sixth buckle holes 914 at differentpositions, thus adjusting the magnitude of pressure F of the elasticfixing portion 910. For more information about the fixing member 920,please refer to the fixing member 620 shown in FIG. 7 .

The buckle 921 is disposed in conjunction with the sixth buckle hole(s)914. In some embodiments, the number of buckles 921 is two so that thebuckles 921 can be correspondingly inserted into two sixth buckle holes914 of the same group. Specifically, the way of double buckles 921 maymake the overall deformation of the first band body 911 and the secondband body 912 relatively uniform.

Specifically, when the buckles 921 insert into the corresponding twosixth buckle holes 914, it is equivalent to that the buckles 921 areinserted into one of the buckle holes 211 as shown in FIGS. 2 and 3 .

In some embodiments, the elastic fixing portion 910 may also include afixing connection portion 916 for connecting the other end of the firstband body 911 to the other end of the second band body 912. The fixingconnection portion 916 is provided with a fixing buckle hole 917 forinsertion of the buckle 921.

The fixing buckle hole 917 is disposed in conjunction with the sixthbuckle hole 914 and the buckle 921. In some embodiments, the number offixing buckle holes 917 is two, and the two buckles 921 are insertedinto the two fixing buckle holes 917 and the two sixth buckle holes 914,respectively.

As shown in FIGS. 9 and 11 , in some embodiments, the first band body911 and the second band body 912 may be arranged in an arc shape. An arclength of the first band body 911 is L1 and an arc length of the secondband body 912 is L2, wherein the arc length L1 of the first band body911 is greater than the arc length L2 of the second band body 912. Alength of the third band body 913 is L3 and a length of the fixingconnection portion 916 is L4.

In some embodiments, the arc length L1 of the first band body 911 may be115 mm-125 mm, and the arc length L2 of the second band body 912 may be105 mm-115 mm. A difference between the arc length L1 of the first bandbody 911 and the arc length L2 of the second band body 912 is 6 mm-10mm. Preferably, the arc length L1 of the first band body 911 is 120 mmand the arc length L2 of the second band body 912 is 112 mm.

A width of the first band body 911 is D1, a width of the second bandbody 912 is D2, and a width of the elastic fixing portion 910 is D3. Insome embodiments, the widths of the first band body 911, the second bandbody 912, and the elastic fixing portion 910 may affect the elasticityof their corresponding structures. For example, when the width of thefirst band body 911, the second band body 912, or the elastic fixingportion 910 is too small, on the one hand, its structure is soft andcannot provide sufficient clamping force for the bone conductionvibrator. On the other hand, if the width of the first band body 911,the second band body 912, or the elastic fixing portion 910 is toosmall, it can also lead to a lower structural strength and is prone tofracture. As another example, if the width of the first band body 911,the second band body 912, or the elastic fixing section 910 is toolarge, its structure is stiffer and provides too much sufficientclamping force for the bone conduction vibrator, which affects thewearing experience. Merely by way of example, in some embodiments, thewidth D1 of the first band body 911 may be equal to the width D2 of thesecond band body 912. For example, the width D1 of the first band body911 or the width D2 of the second band body 912 may be 3 mm, and thewidth D3 of the elastic fixing portion 910 may be 16 mm. In someembodiments, the width D1 of the first band body 911 or the width D2 ofthe second band body 912, and the width D3 of the elastic fixing portion910 are not limited to the above-mentioned values and can be adaptedaccording to their material and the wearing object.

In the embodiment of the fixing assembly for bone conduction vibratortesting, when the guinea pig is the wearing object, the head structureof the guinea pig may be approximated as a cone-shaped structure. Thatis, a head circumference in front of the guinea pig's ear issignificantly different from a head circumference behind the ear. Ifboth the first band body 911 and the second band body 912 are linearband structures, this may result in one of the first band body 911 andthe second band body 912 exerting too much pressure on the guinea pig'shead and the other exerting too little pressure on the guinea pig's headwhen the guinea pig is wearing the fixing assembly. In some embodiments,the first band body 911 and the second band body 912 may be in aconcentric circular arc setting, which allows the first band body 911and the second band body 912 to have different lengths, so as to besuitable for testing experiments with the bone conduction vibrator onthe guinea pig. In some embodiments, the lengths of the first band body911 and the second band body 912 and angles of the circular arcs (thecircular angles) may be determined based on the head circumference infront of the guinea pig's ear and the head circumference behind the ear.Specifically, according to the arc length L1 of the first band body 911,the arc length L2 of the second band body 912, the width D1 of the firstband body 911, the width D2 of the second band body 912, and the widthD3 of the elastic fixing part 910, the circular angle of the first bandbody 911 may be calculated according to the following equation:

$\begin{matrix}{{{\frac{2\pi r}{360{^\circ}} \times x} = {L1}},} & (2) \\{{\frac{2{\pi\left\lbrack {r - \left( {{D3} - {D1}} \right)} \right\rbrack}}{360{^\circ}} \times x} = {L2.}} & (3)\end{matrix}$

According to equation (2)-equation (3), the following formula may beobtained:

$\begin{matrix}{{x = \frac{\left( {{L2} - {L1}} \right) \times 360{^\circ}}{2\pi\left( {{D3} - {D1}} \right)}},} & (4)\end{matrix}$

where x denotes the circular angle of the first band body 911 and rdenotes a radius corresponding to the circular angle of the first bandbody 911. Similarly, using the above equations, the circular angle ofthe second band body 912 may be calculated.

In some embodiments, the circular angle of the first band body 911 maybe 32 degrees-36 degrees, and an absolute value of a difference betweenthe circular angle of the first band body 911 and the circular angle ofthe second band body 912 is less than 2 degrees. In some embodiments,the circular angle of the first band body 911 may be 32 degrees-35degrees. In some embodiments, the circular angle of the first band body911 may be 32 degrees-34 degrees. Preferably, the circular angle of thefirst band body 911 may be 33 degrees. In some embodiments, the absolutevalue of the difference between the circular angle of the first bandbody 911 and the circular angle of the second band body 912 is less than1.5 degrees. In some embodiments, the absolute value of the differencebetween the circular angle of the first band body 911 and the circularangle of the second band body 912 is less than 1 degree. Preferably, theabsolute value of the difference between the circular angle of the firstband body 911 and the circular angle of the second band body 912 is lessthan 0.5 degrees. Further, a hole spacing between two adjacent sixthbuckle holes 914 along the length direction of the third band body 913is L, and a hole spacing between the sixth buckle holes 914 in the samegroup is D4. It should be noted that the wearing object is not limitedto the above-mentioned guinea pig, and the wearing object or testingobject may also be other individuals. When the fixing assembly is wornon other individuals, the lengths of the first band body 911 and thesecond band body 912 or the corresponding circular angles may beadjusted adaptively. For example, the first band body 911 and the secondband body 912 may both have a linear band structure, and the two may bearranged approximately in parallel.

As shown in FIG. 12 , the fixing assembly 900 may also include a fixingbase 930 provided on the side of the bone conduction vibrator away fromthe wearing object. The fixing base 930 is further provided with a firsthook member 931 and a second hook member 932 extending away from thebone conduction vibrator. In some embodiments, the fixing base 930 maybe the aforementioned connection portion 130.

In some embodiments, the first hook member 931 and the second hookmember 932 are disposed at intervals from each other along an intervaldirection of the first band body 911 and the second band body 912. Oneend of the first hook member 931 fixedly disposed on the fixing base 930is a fixing end 9311 of the first hook member 931, and the end of thefirst hook member 931 away from the fixing base 930 extends toward thesecond hook member 932 to form a free end 9312 of the first hook member931. One end of the second hook member 932 fixedly disposed on thefixing base 930 is a fixing end 9321 of the second hook member 932, andthe end of the second hook member 932 away from the fixing base 930extends toward the first hook member 931 to form a free end 9322 of thesecond hook member 932. An opening 933 is formed between the free end9311 of the first hook member 931 and the free end 9322 of the secondhook member 932.

Specifically, the opening 933 may be the shortest distance between thefree end 9312 of the first hook member 931 and the free end 9322 of thesecond hook member 932. An interval distance between the fixing end 9311of the first hook member 931 and the fixing end 9321 of the second hookmember 932 is a distance between a point where the fixing end 9311 ofthe first hook member 931 is closest to the fixing end 9321 of thesecond hook member 932 and a point where the fixing end 9321 of thesecond hook member 932 is closest to the fixing end 9311 of the firsthook member 931. The interval distance between the first band body 911and the second band body 912 is the width D3 of the elastic fixingportion 910.

In some embodiments, the opening 933 may be smaller than the intervaldistance between the first band body 911 and the second band body 912 sothat the elastic fixing portion 910 is not easily detached from thefixing base 930 when the first band body 911 and the second band body912 are set between the first hook member 931 and the second hook member932 through the opening 933.

In some embodiments, the interval distance between the fixing end 9311of the first hook member 931 and the fixing end 9321 of the second hookmember 932 is greater than the interval distance between the first bandbody 911 and the second band body 912.

In some embodiments, the first hook member 931 and the second hookmember 932 may be fixed to the fixing base 930 via a convex table. Adistance between the convex table provided with the first hook member931 and the convex table provided with the second hook member 932 may begreater than, less than, or equal to the interval distance between thefirst band body 911 and the second band body 912.

As shown in FIG. 13 , when the elastic fixing portion 910 is provided incooperation with the fixing base 930, the first band body 911 and thesecond band body 912 are disposed in an accommodation space formed bythe free end of the first hook member 931, the free end of the secondhook member 932, and the fixing base 930. The first hook member 931 andthe second hook member 932 are used to limit the positions of the firstband body 911 and the second band body 912.

In the embodiment of the fixing assembly for bone conduction vibratortesting, a guinea pig may be used as a wearing object. The boneconduction vibrator is pressed onto the head of the guinea pig via anelastic fixing portion (e.g., the elastic fixing portion 210 shown inFIG. 2 or FIG. 3 , the elastic fixing portion 410 shown in FIG. 4 , theelastic fixing portion 510 shown in FIG. 5A, and the elastic fixingportions shown in FIG. 6 and FIG. 9 ). The bone conduction vibratortransmits an audio signal to the guinea pig. A brain signal generated bythe guinea pig in response to the vibration signal transmitted by thebone conduction vibrator is detected, and the brain signal is a feedbacksignal from the wearing object. The signal transmission performance ofthe bone conduction vibrator is determined by comparing the brain signalwith a preset signal intensity. As used herein, the brain signal is atest signal obtained by testing the brain of the wearing object afterreceiving the audio signal, the intensity of the brain signal is anamplitude of the test signal, and the preset signal intensity is apreset amplitude. When the amplitude of the test signal is greater thanor equal to the preset amplitude, it can be considered that the wearingobject can effectively obtain the information contained in the audiosignal after receiving the audio signal.

Specifically, when the pressure F is less than the minimum threshold,the intensity of the brain signal is less than the preset signalintensity at this time; when the pressure F is equal to the minimumthreshold, the intensity of the brain signal is equal to the presetsignal intensity at this time; when the pressure F is between theminimum threshold and the maximum threshold, the intensity of the brainsignal is greater than the preset signal intensity at this time; whenthe pressure F is equal to the maximum threshold, the intensity of thebrain signal is equal to the preset signal intensity at this time; andwhen the pressure F is greater than the maximum threshold, the intensityof the brain signal is less than the preset signal intensity at thistime.

Since the pressure of the bone conduction vibrator pressing against thewearing object can affect the intensity of the feedback signal of thewearing object, when the pressure of the bone conduction vibratorpressing on the wearing object is between the minimum threshold and themaximum threshold, the intensity of the detected brain signal is greaterthan or equal to the preset signal intensity. By fixing the fixingmember fixed at one end of the elastic fixing portion to the secondposition on the elastic fixing portion, it can ensure that thetensioning force of the elastic fixing portion is within the thresholdrange (between the minimum threshold and the maximum threshold), so asto avoid the problem that the intensity of the feedback signal is nothigh due to the pressure of the bone conduction vibrator on the wearingobject is too small or too large.

In some embodiments, the fixing assembly may be used in a boneconduction earphone (e.g., a headband bone conduction earphone). Forexample, the fixing member fixes the elastic fixing portion around thehuman head. An acoustic output unit of the bone conduction earphone isalways pressed near the human ear (e.g., front, back, upper, or lowerside of the auricle, etc.) by the elastic fixing portion. The audiosignal output by the acoustic output unit of the bone conductionearphone is transmitted to the human body through the bones, muscletissues, blood, etc., and is perceived by the auditory nerves of thehuman body. In some embodiments, a connection position between thefixing member and the elastic fixing portion may be adjusted accordingto the human body's wearing feeling, so as to adjust the tensioningdegree of the elastic fixing portion and make the wearing experiencemore comfortable. The fixing assembly may make the bone conductionearphone adapt to different users. While enhancing wearing comfort, byadjusting the tensioning degree of the elastic fixing portion, thepressure of the bone conduction earphone on different human bodies canbe within the preset pressure range, so as to avoid the pressure of thebone conduction earphone on the human body is too small, resulting in apoor audio signal received by the human body, or the pressure of thebone conduction earphone on the human body is too large, resulting inthe unsuitable wearing of the bone conduction earphone. It should benoted that different users who wear the bone conduction earphone mayhave different threshold ranges and preset ranges of the tensioningforce, which can be determined according to the actual needs.

In some embodiments, the fixing assembly may also be applied to thewearing of a watch or pedometer. For example, the fixing member fixesthe elastic fixing portion around a wrist of the human body. In someembodiments, the connection position between the fixing member and theelastic fixing portion may be adjusted according to the feeling of thehuman body wearing the watch or pedometer, so that the tensioning degreeof the elastic fixing portion can be adjusted to make the watch orpedometer more suitable for wearing, and the fixing assembly can adaptthe watch or pedometer to different human bodies. In some embodiments,the fixing assembly may also be used for the wearing of an oximeter orblood pressure monitor. The fixing member fixes the elastic fixingportion around to a human wrist or large arm so that the oximeter orblood pressure monitor can always be pressed against the human skinunder the action of the elastic fixing portion during human activity toobtain a blood oxygen content or blood pressure under the skin of thehuman body. In some embodiments, according to the human body's wearingexperience, the connection position between the fixing member and theelastic fixing portion may be properly adjusted, thereby adjusting thetensioning degree of the elastic fixing portion and making the wearingexperience more comfortable.

The present disclosure also provides a wearing device, and the wearingdevice may include a fixing assembly and a bone conduction vibrator. Insome embodiments, the fixing assembly may include an elastic fixingportion and a fixing member. The elastic fixing portion is a bandstructure. The elastic fixing portion includes a first position and asecond position. The first position and the second position are disposedat intervals along a length direction of the elastic fixing portion. Thefixing member fixes the elastic fixing portion around the wearing objectso that the bone conduction vibrator is disposed between the elasticfixing portion and the wearing object. When the elastic fixing portionsurrounds the wearing object and is in a natural state, the fixingmember fits into the first position of the elastic fixing portion. Whenthe fixing member fits into the second position, the elastic fixingportion provides a pressure for the bone conduction vibrator to act onthe wearing object, and the pressure is within a preset pressure range.It should be noted that the fixing assembly of the wearing device may besimilar to the fixing assembly 200, the fixing assembly 400, the fixingassembly 500, the fixing assembly 600, or the fixing assembly 900 and isnot repeated herein. The wearing device is described below in connectionwith the fixing assembly of FIG. 14 .

The wearing device 1400 fixes the bone conductionvibrator 1440 to the head of the lab rat via the fixing assembly toachieve the bone conduction vibrator testing on the lab rat.

In some embodiments, the fixing assembly includes an elastic fixingportion 1410 and a connection portion. The elastic fixing portion 1410includes a first band body 1411 and a second band body 1412. The firstband body 1411 is used to elastically surround at least a portion of thehead of the lab rat, and the second band body 1412 is used toelastically surround at least a portion of the neck of the lab rat. Insome embodiments, the first band body 1411 is elastically surroundedaround the head of the lab rat on the front side of the lab rat's ear,and the second band body 1412 is elastically surrounded around the neckof the lab rat on the back side of the lab rat's ear.

In some embodiments, thebuckle includes a first buckle and a second buckle disposed at intervalsfrom each other along an interval direction of the first band body 1411and the second band body 1412, wherein the first buckle is inserted intothe first buckle hole and the second buckle is inserted into the secondbuckle hole.

Specifically, the steps of using the elastic fixing portion 1410 inconjunction with the fixing member are as follows: firstly, setting thefixing member in the center of the head of the lab rat so that adistance from the bone conduction vibrator to the left ear is equal to adistance from the bone conduction vibrator to the right ear; secondly,setting the connection band body against the lower jaw of the lab rat;thirdly, elastically stretching the first band body 1411 at any sidealong the front side of the ear of the lab rat until the first buckle isinserted into any first buckle hole on the first band body 1411;fourthly, elastically stretching the first band body 1411 at the otherside along the front side of the ear of the lab rat until the firstbuckle is inserted into another first buckle hole in the same group asthe first buckle hole in the third step above; fifthly, repeating thethird and fourth steps so that the second buckle is inserted into thesecond buckle hole in the same group as the first buckle hole in thethird step, thereby fixing the bone conduction vibrator to the top ofthe lab rat's head.

In some embodiments, the elastic fixing portion 1410 further includes athird band body (refer to the third band body 913 in FIG. 9 ). One endof the first band body 1411 and one end of the second band body 1412 arejointly connected to the third band body. The other end of the firstband body 1411 and the other end of the second band body 1412 arejointly connected for fixing. In some embodiments, the elastic fixingportion further includes a fixing connection portion (refer to thefixing connection portion 916 in FIG. 10 ) for connecting the other endof the first band body 1411 to the other end of the second band body1412. The fixing connection portion is provided with a fixing bucklehole, and the fixing buckle hole is provided for the buckle to insert.In some embodiments, the fixing assembly may further include a fixingbase (refer to the fixing base 930 in FIG. 9 ). The fixing base isfurther provided with a first hook member and a second hook memberextending away from the bone conduction vibrator. The first hook memberand the second hook member are disposed at intervals from each otheralong the interval direction of the first band body 1411 and the secondband body 1412. One end of the first hook member fixedly disposed on thefixing base is a fixing end of the first hook member, and the end of thefirst hook member away from the fixing base extends toward the secondhook member to form a free end of the first hook member. One end of thesecond hook member fixedly disposed on the fixing base is a fixing endof the second hook member, and the end of the second hook member awayfrom the fixing base extends toward the first hook member to form a freeend of the second hook member. An opening is formed between the free endof the first hook member and the free end of the second hook member.
